Hi,

if you did not assign a value to lambda, the plot command does not know
what to do with the symbilc values.

Try

Manipulate[
  With[{\[Lambda]=1},
   ...
]]

or add a slider for lambda too:

Manipulate[
  ListLinePlot[
    (* Gamma[1+ y] and y! cancel of course *)
    Table[a^y*\[Lambda]*(a + \[Lambda])^(-1 - y), {y, 0, 10}],
    PlotRange -> {0, 1}, DataRange -> {0, 5},
    PlotMarkers -> Automatic
  ], {a, 0.01, 1, 0.01}, {{\[Lambda], 1}, 0, 2, 0.05}
]


hth,
  Peter
